Compounds
Form of matter that cannot be broken down into a simple form.
What is an “element”?
An atom or group of atoms that has a positive or negative charge.
What is an “ion”?
An ordered, repeated pattern of ions that forms a crystal.
What is a “crystal lattice”?
A bond formed when valence electrons are SHARED between atoms.
What is a “covalent bond”?
Bond formed when two atoms share one pair of electrons.
What is a “single bond”?
A pure substance made of two or more elements, combined in fixed amounts.
What is a “compound”?
The rule which helps explain why atoms gain or loose electrons to form stable ions, which have eight valence electrons.
What is the “octet rule”?
Attraction between positive metal ions and their valence electrons.
What is “metallic bonding”?
Smallest particle that has the properties of an element.
What is an “atom”?
Bond formed when two atoms share two pairs of electrons.
What is a “double bond”?
How atoms are joined together by sharing, gaining or loosing valence electrons in compounds like water, or elements like aluminum foil.
What is a “chemical bond”?
Bond that holds a negatively charged ion and a positively charged ion together.
What is an “ionic bond”?
Properties describing how metals bend and conduct electricity due to their “sea of electrons”.
What is “malleability” and “ductility”?
A group of two or more atoms that are joined by covalent bonds.
What is a molecule”?
Bond formed when two atoms share six electrons.
What is a “triple bond”?
Substance made up of different substances, but is not held together by chemical bonds like a compound.
What is a “mixture”?
Positive ions.
What are “cations”?
Solid solution of metals, or a metal and non-metal.
What is “alloy”?
This determines how many bonds an atom can form.
What is “however many electrons they need to form the nobel gas configuration”?
The most common compound on Earth, which we need to live.
What is “water”?
Negative ions.
What are “anions”?
Five properties of ionic compounds.
What is: Crystal at room temperature; High melting and boiling points; Brittle; Dissolve in water; Good insulators in solid state?
